Interaction of BI 425809 With Midazolam, Warfarin, Omeprazole and Digoxin

A Study to Investigate the Effects of Multiple Doses of BI 425809 on the Single Dose Pharmacokinetics of Cytochrome P450 Substrates (Midazolam, Warfarin and Omeprazole) and a P Glycoprotein Substrate (Digoxin) Administered Orally in an Open-label, One-sequence Trial in Healthy Male Subjects

To assess the influence of multiple doses of BI 425809 on single dose pharmacokinetics of midazolam (CYP3A4 probe drug), warfarin (CYP2C9 probe drug), omeprazole (CYP2C19 probe drug) and digoxin (P-gp probe drug)

Inclusion criteria:

• Healthy male subjects according to the investigators assessment, based on a complete medical history including a physical examination, vital signs (blood pressure (BP), puls rate (PR)), 12-lead electrocardiogram (ECG), and clinical laboratory tests
• Age of 18 to 55 years (incl.)
• Body Mass Index (BMI) of 18.5 to 29.9 kg/m2 (incl.)
• Signed and dated written informed consent prior to admission to the study in accordance with good clinical practice (GCP) and local legislation
• Ready and able to use highly effective methods of birth control that result in a low failure rate of less than 1% per year when used consistently and correctly. A list of contraception methods meeting these criteria is provided in the subject information

Exclusion criteria:

• Any finding in the medical examination (including blood pressure (BP), puls rate (PR) or electrocardiogram (ECG)) is deviating from normal and judged as clinically relevant by the investigator
• Repeated measurement of systolic blood pressure outside the range of 90 to 140 mmHg, diastolic blood pressure outside the range of 50 to 90 mmHg, or pulse rate outside the range of 50 to 90 bpm
• Any laboratory value outside the reference range that the investigator considers to be of clinical relevance
• Any evidence of a concomitant disease judged as clinically relevant by the investigator
• Gastrointestinal, hepatic, renal, respiratory, cardiovascular, metabolic, immunological or hormonal disorders
• Cholecystectomy and/or surgery of the gastrointestinal tract that could interfere with the pharmacokinetics of the trial medication (except appendectomy and simple hernia repair)
• Diseases of the central nervous system (including but not limited to any kind of seizures or stroke), and other relevant neurological or psychiatric disorders Further exclusion criteria apply
